Fall Aeration: September 12-15

Fall Aeration Process
We have started preparations for the September 12th to 15th aeration process. Many cultural practices for the golf course turf are determined depending on the health, priority, maintenance needs and, of course, the weather.  Fertilization and fungicide applications are also timed to aid in the recovery process and can be applied before, during or after the aeration process.  Listed below is a summary of the processes we plan to accomplish on specific areas of the golf course:

Greens 

  • Spray a soluble fertilizer the day before aeration.
  • Deep tine with ½ inch tines to a depth of 9 to 10 inches. Start Monday night after shotgun and finish Tuesday morning. This process improves root growth and drainage.
  • Punch with ½ inch hollow tines if the new turf allows and doesn’t puff or lift the surface; we may have to change to solid tines if root development is unstable. If cored they will be collected and used to establish a new nursery green on the turf farm. We also plan to have cores delivered from VGC for the nursery green.
  • Apply 1mm premium dry sand to the surface and brush and or mat into the holes and rolled until a level surface is acquired. Irrigation is added to help settle sand into aeration holes. More sand is added the next day where needed and matted and rolled again.
  • Bentgrass over-seeding will be done at a rate of 1.5 lbs per 1000 square feet.
  • Fungicides and fertilizers will be applied as needed over the next 10 days.
  • Greens 1, 7 and 15 will not be in the aeration rotation as we will have slit drainage installed in these greens during the closure and into the following week. These greens will be open for play within a few days after installation. We will vent the green surfaces between the slit drains after install with ¼ inch solid tines.

  Approaches and Par 3s

  • Approaches are verti-cut to a depth of ½ inch to remove surface thatch.
  • Thatch debris is removed with blowers and vacuumed up.
  • Sand and seed is applied and is then punched with 5/8 solid tines and matted in.
  • Fertilizer and irrigation are added as needed.

Green Surrounds

  • Surrounds are punched with 5/8 inch solid tines.
  • Seed is applied before sand top-dressing and brushed in when dry.

Fairways

  • Fairways 1, 3, 5, 6, 7, 8, 9, 10, 13.
  • 3mm sand is spread on the fairway surfaces including the immediate roughs.
  • 7/8 inch solid tines are punched to a depth of 9 inches.
  • When sand is dry it is brushed into holes and low areas.
  • Sprinklers need to be blown clean of sand so irrigation can be applied.
  • Over-seeding will be done on selected areas.
  • Fairways 2, 12, 15, 17, 18.
  • 3/4 inch hollow tine will be done on these fairways.
  • When the cores dry a large metal mat will be dragged across the cores several times to release any sand back into the aeration holes.
  • The remaining thatch will be blown into rows and collected for removal.
  • 3mm sand will be applied to complete the filling of holes and level the surface and when dry will be brushed in.
  • Sprinklers need to be blown clean of sand so irrigation can be applied.
  • Over-seeding will be done on selected areas.
  • A starter type fertilizer will be applied on all fairways within 5 to 7 days.

Tees

  • Tees are punched with 5/8 solid tines.
  • Top-dressed with 1mm sand and over seeded with ryegrass.
  • Sand and seed is brushed in to fill holes and create a level surface.
  • Fertilizer and irrigation are added as needed.

All sprinklers, quick couplers, valve covers, catch basins and yardage markers must be cleaned and marked with covers and flagged to prevent damage.

All sprinkler heads must have sand debris cleaned daily before irrigation can be used.
